Total snowfall so far this year at Mount Baker is 102 inches, Haner said.

Snow also fell Friday in the eastern third of the state, including Spokane. But a "rain shadow" kept the Columbia Basin, including Moses Lake, in the clear.

The snow should taper off for a drier weekend across Washington, Haner said Friday. More rain and mountain snow are forecast to move in to Western Washington Sunday afternoon and spread east by evening.

The heavy snow Thursday afternoon closed eastbound lanes of Interstate 90 at Snoqualmie Pass for a time. Chains were required for a spell Friday morning, even on four-wheel drive cars, on the state's main east-west highway. The Transportation Department changed that to a traction tire advisory for Snoqualmie Pass, as well as for Stephens and White passes. Big rigs still had to chain up, and oversize loads were prohibited until the roadways cleared.

The snow is good news to skiers and snowboarders and Cascade ski resorts.

The White Pass ski resort opened Friday. Stevens, Mount Baker and Crystal Mountain were already open but waiting for fresh snow. The most convenient resort to Seattle, the Summit at Snoqualmie, said that Summit West would open this weekend.
